In MVC 4 we have bundles. While defining the bundles we can use wildcards like * for all files in a folder.
In the example below what does -{version} mean?
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
}

The
-{version}basically maps to a version regex, or to be precise:(\d+(?:\.\d+){1,3}).Using
*tends to grab too much, for example if you bundlejquery*, that will includejquery-uias well which might mess up the ordering. But usingjquery-{version}.jswould let you avoid having to update your bundle definition every time you upgrade jquery.Additional things to note:
{version}only works for the last part of the path--basically the file name--not a directory.
